Brief description: AI wingmen not working properly on takeoff

 

 

Detailed description

Started a new campaign in 1942 Stalingrad map as Russia. Flying IL-2 1941. I'm 4th in group. Set to takeoff from runway. As soon as I get ingame, all four aircraft are lined up on runway as you would expect. But then Flight Lead immediately asks for clearance to taxi, turns around and crashes into his wingman. Mission file attached.

Then here's another one: https://drive.google.com/file/d/1l4ygSrGTMVDA0jNHTMdr4JACQu5YWwck/view?usp=sharing

 

American Mustang campaign, Normandy, Bomber Escort

 

This one is very similar to the last.

 

Very early in the mission, 4 of the escorts made that big looping turn and fell behind. Flight leader heads back, finds them, then circles. The bombers were still relatively close, but he started circling. The 4 "missing" escorts had no problem catching the bombers.....the flight leader circled. We were crossing the French coast and he was still circling over the English coast. After crossing the coast, 6 of the escort fighters start doing "The Dance of Death". 2 collisions before the target, and 1 right after we turned for home and 6 escorts are down. My flight leader finally got back and weaved protectively over the bombers all the way home. 

The Germans were a no show again.....and we still lost 6.....again.

 

I have noticed this issue as well with Normandy campaign. I have not seen this behaviour with Moskow or Stalingrad oddly enough. Mission attached. Short track clip which shows the P47's zig zagging above the bombers on close to co altitude.

Added: this behavior only happens after the bombers dropped their bombs and turn to home.

Yes, I noticed this yesterday too in a new P-47 career, thanks. ?

OK, stop me if you've heard this before....

 

American Mustang campaign, Normandy map, bomber escort mission.

 

2 of the escorts fall behind; the escort flight leader goes back to see what they're up to and he.....circles. The rest of us continue on to the target. Shortly after we start towards home, "The Dance" begins. 6 of them, just above the bombers. The first collision claims 4....it was impressive. The escort "flight leader" stops circling and races to rejoin us. When he arrives, he takes position above the 2 remaining dancers. They continue to dance....and touch lightly.....1 suffers wing damage but is able to continue.....the other suffers engine failure and the pilot bails over friendly territory.

 

1 KIA, 3 MIA, 5 planes destroyed, 1 damaged. The only sign that I saw of the enemy was 88mm flak bursts.

 

I hate to sound like a broken record, but as I stated in 1 of my earlier posts, when the escort flight leader "goes missing" bad ---- happens.

 

I've seen 2 different behaviors from the flight leader when some escorts fall behind which may (or not) be relevant.

 

In most of the missions he'll go back and "herd" the stragglers forward until everybody is back in position.
To do this, he'll stay on course with the bombers, but he'll throttle back and slowly fall back until he's behind the straggling escorts. He'll then throttle back up and follow them back to the bomber formation. I've seen this happen multiple times in the same mission and as long as it happens this way, everything works.

 

Sometimes the flight leader makes a big looping turn (like the other escorts do that puts them way behind). This may be when he "gets lost", but I need to try to confirm that.

In an intercept ground attack aircraft mission in a 109 Moscow career I was attacked by two Migs, while I was taxiing to the parking area after landing. The Migs completely ignored my two squadmates flying their landing pattern, who also ignored the two Migs. The Migs were able to fly two strafing runs at my 109 before I exited the mission.

Brief description: Paradrop speed too high
Detailed description, conditions: When given the "Attack Area" command in order to drop paratroopers, the C-47 will accellerate to approximately 200mph regardless of which speed it was originally flying. 200mph is nearly twice the historical speed at which a paradrop should happen, and in real life would likely have deadly consequences.

Expected behaviour: The C-47 should either maintain the speed of the previous waypoint, or drop to around 110 mph when dropping paratroopers.

One of our mission designers looked into this, and this is what he had to say:

 

"I made a test example, everything happens differently, sometimes each of the interceptors takes one plane, sometimes two at a time. In the attack commands everywhere checkbox "Attack group" is on. Sometimes a plane does not have time to switch from land to combat trajectory, sometimes, it's the opposite. In general, in my opinion, this is not a bug."

Brief description: Issue with behaviour of wingmen on escort missions.

 

Detailed description, conditions: On escort missions your wingmen don´t commit properly to a fight with the attacking enemy fighters when they´re too far away from the  friendly bombers or attackers you have to protect. Your wingmen constantly switch between "engaging the enemy" and "race after the friendly bombers or attackers" what results in most cases in not shooting the enemy at all while the enemy has an easy time shooting down your flight.

 

Additional assets (videos, screenshots, logs): I attached the the mission file below. Again I flew the escort mission with the I. JG3 based at Pitomnik but it seems like that the issue appears with every mission (more or less) no matter which career / unit / aircraft.

Almost half a year later i have to ask again if there are any fixes coming in the near future? Because to this day there are still the exact same issues going on which mess up the career mode like nothing else.

It's been like this for a long time, which means it's not an easy thing to fix.

Brief description: Tank Crew AI Assault Guns like _SU-122 and _SU-152 do not turn to face targets
Detailed description, conditions: Vehicles without turrets, do not turn towards threat, only move their limited traverse guns. That way they are ineffective against player tanks like Tigers.
How to reproduce:
In Quick Mission Builder have enemy SU-152 assault guns vs you in a own tank. Flank and approach enemy assault gun from side. In 3rd person you can see the gun try to aim at you, but it can not since the field of fire is to limited. The assault gun drives forward ignoring you.

I have almost the same issue in the "Sea Dragons" and "Lighting Strikes" campaign. In both cases, the auto Pilot keeps on circling the empty runaway endlessly instead of trying to land.

Brief description: have noticed in career mode that the autopilot tends to keep making attack runs against air targets or ground targets even after all ammunition has been used up.

Detailed Description: I started using the campaign mode recently. So far, I have mainly used the Normandy setting. I don't know how it is in the other maps, but instances where the autopilot acts as if the plane still has ammunition, even though it does not, are common.

Normandy (career) > UK > 15.04.1944 (start date) > 308th Squadron > Deanland Airfield > Spitfire MK.IXc.

 

Bombers escort mission.

 

Squadron leader fires numerous flares, opens the airplane cockpit, that's it. 

 

"Requesting taxi to runway, over."

"Negative, runway is busy, hold position".

 

There are no planes on the runway except ours, none near the airbase, or above. 

 

Missions in this career can only be played when selecting mission start: in air. 

 

/Edit 1. Works now, after I played a different mission in between the bombers escort.

 

/Edit.2 AI leader refuses to start on intruder mission, only after I start myself, rest follows, and circles above the airfield forever.

Next try. First airplane moves to the back of the formation, AI starts and circles above the airfield forever.

For some reason, both times, there was a jeep on the edge of the runway in front of us. 

 

Again... start in air to be able to play.

/Edit 1. @LukeFF

 

I'm in Chailey airbase now, beside mission attached, bombers escort doesn't work either. Maybe I will upload more, but that just gets on my nerves. Start a mission on the ground, see it doesn't work, force shutdown of il-2.exe, restart the game, but now start in air... it works, play a bit, repeat.

 

Moscow career on German side had no issues related to missions, neither did Normandy career on US side. 

 

/Edit 2.

 

On bomb railway junction mission, leader crashes as visible on the attached screen*. Both damaged and unable to fly airplanes despawn, mission continues and AI circles above the airfield forever.

 

*He instantly turned left after the start, as if he wanted to go to the back of the formation, but instead of going the usual safe right side, he went left now.

So, this is a PWCG issue. Paraphrasing one of our mission designers:

 

"The taxi graph in career mode is different, and it works. A bug in the group with the airfield used in PWCG. Due to the large distance between the VPP point and the leader, the leader steers toward it, which leads to collisions. The VPP point should be near the leader or in the middle of the group." 

 

@PatrickAWlson

[PatrickAWlson]

@LukeFF Taxi graph - is that for cold start?  If yes, cold start is not supported in PWCG.  It was implemented for some maps and I have not ripped it out, but it is not being worked anymore.

 

If this issue is for runway starts then I am not sure how a taxi graph comes into play.

[LukeFF]

One more bit of information that may help:

 

"The VPP point is far from the leader, so he steers toward it."

Brief description:

AI speed is too low on their way to waypoints (bombers)

Detailed description, conditions:

Haven't noticed that much of a discrepancy when on Frontline patrol missions or Free hunt, with fighter groups maintaining ~210-220 mph IAS. Assuming that waypoint speeds are given in TAS, I put the approximate data for such sorties into IAS -> TAS calculator and got 255-260 mph, so more or less spot on.

But when bombers fly, they nearly stall themselves and fighters alongside as well by flying around 160-170 mph IAS, and that's at just 3000 feet. With bombs dropped. So yeah, sorry if this point has been brought up, but wanted to highlight it just in case.

P.S. - It doesn't have anything to do with damaged bombers, they were just as slow on their way to the bombing point. Had to keep my throttle at 25-27% not to skip ahead.
